Recent Results Of Proton Drip‐Line Studies At The HRIBF Recoil Mass Spectrometer

The observation of fine structurein proton emissionallows one to measure the composition of the parent state’s wavefunction and the deformation of the daughter state. A systematic study of proton‐unbound nuclei in the rare earth region is ongoing at the HRIBF. Newly discovered fine structurein the decays of 145Tm and 141Ho are discussed, as well as advances in our experimental equipment.
